Filters to protect AC Freon recovery machine

JD Seller · Jul 11, 2019

I told my son to get filters on the AC Recovery machine to protect it from systems with the stop leak in them. When we were working mainly on farm related equipment we rarely ran into the stuff. Now that he is more into auto repairs he is finding it in a lot of them. He plugged the main filter up on the machine this last week. Those are $150 each.

I know some auto tech guys posted about them several years ago. I can not find them when searching. What I am finding on the internet has me confused as to what we want or need. I am thinking they need to be on the high and low side hoses. They would need to be between the vehicle and the recovery unit.

IRC the earlier post talked about them being basically an economical, throw away filter.

No advice on where or from who. Build the cost into the customer's bill with a pre warning on the work order stating systems found to contain leak stop or dye will be charged for filtration and shop costs, up to $XXX.XX Jim

What era of vehicles are we dealing with, and what refrigerant?

What issues are we dealing with that leave a system full of refrigerant, but not functioning?

I'm certified and have R-12 and R-134A recovery equipment, but seldom use it, as most stuff that shows up with problems is devoid of refrigerant.

Now back to your family problem, GOOGLE "Sporlan filter" and find a good-sized one and come up with matching fittings to get it in-line, ahead of your son's machine.

Bob we are certified in R-12 and R-134 as well. My son is looking ahead to the newer types of Freon but that is all his baby. LOL We mainly use the recovery equipment when finding leaks in systems we are repairing. A system can set and hold vacuum for hours/days but leak under high pressures on hot days.

Yes Sporlan makes economical filters to do what you want. If pulling from both sides you would want one on each line. I just pull from the low side so just one.

Around here no one will touch it if you admit you have used a sealer. Plug a filter because they didn't and they eat the cost.

When I put them on my machine they were $250 apiece... I put them on the high and low side I brought a new machine and have not swapped them from the old to the new yet...

My machine has a large filter in it but I use filter/driers inline with my hoses. I was told that would help protect the main filter. ( ASE certified and universal certification for industrial applications)

IIRC, I think TimS has talked about using nitrogen to find leaks in them.

And if the system isn't devoid of refrigerant some fly by night HVAC guys will put the hose a glove, hide the glove under a rock and in in short time the system is devoid of refrigerant.

Mike< Thanks for the reply. We do that as well but the Freon sometimes will leak out where the nitrogen will not.

We run a lot of industrial refrigeration equipment at work and I work closely with our refrigeration people. Seen nearly all of it.
Oil seeping through gaskets where refrigerant wouldn t.
Saw a system run for 2 years with one braze joint not brazed, how it passed the leak test we have no idea.
Recently saw a commercial dehumidifier that the evaporator coil would start leaking when over 200 psi, R410A system, when equalized it was over 250 psi. It was difficult to find.

I m not sure sporlan makes a solution to catch the type of crud, they are meant to be installed in the system for moisture and basic filtration.
